Please try the plug-in and not the stand alone. I consistently get washed out, pinkish results with both raw and JPEG files even on photos that under 3.2 worked fine. Thanks

Thanks for the replies. I continue to have problems not just with new photos but with photos taken in the past that under 3.2 worked fine with the plug-in. These include both RAW and JPEGs. There are some HDR shots taken in the past, however, that have no problems at all. There is something wrong but just haven’t nailed it down yet. Will contact photomatix as sadly for me the issue is quite real and perplexing.

Problem solved with the help of Photomatrix.com. When I upgraded to Aperture 3.3 I had set the ‘External Editor Color Space’ to my printer, a Canon IP6000 PR1. Evidently with the hues in some photos the plug-in would add the odd color wash. When the external editor color space preference in Aperture 3.3 was set to No Profile Selected, the problem was resolved. I’m not sure whether this problem would apply to other printer settings but it probably is worth checking if anyone is having a similar problem. This problem occurred with some of my photos, particularly those with a “golden hue,” but not with others so the problem indeed is an intriguing one
